Deliverable 6.3 summarizes the outcomes obtained for Subtask 6.4.2: “DSF interface development”. The MareFrame DSF (Decision Support Framework) is a pragmatic planning process, and the DSF interface software makes the necessary information and tools available within this process. For each case study, the DSF interface integrates information from the ecosystem models (Ecopath with Ecosim, Gadget, and/or Atlantis) with Multi-Criteria Analysis (MCA) and Bayesian Belief Networks (BBN) decision tools into a common framework.
